Abstract  Abstract

Invention Patent: <B> METHOD AND DEVICE FOR ADAPTIVE SEARCH FOR BANDWIDTH PITCH IN THE CODING OF BROADBAND SIGNS <D>. The present invention relates to an improved pitch search method and device for digitally encoding a broadband signal, in particular, but not exclusively, a speech signal, in the sense of transmitting, or storing, and synthesizing this sound signal broadband. The new method and device that achieves efficient modeling of the harmonic structure of the speech spectrum uses several forms of low-pass filters applied to a pitch code vector, the one that produces the greatest forecast gain (that is, the smallest error) is selected. forecasting) and the associated pitch code book parameters are advanced.
